Need Help Wiring a large LED to Run Off Batteries

[taylorbrush]

I'm a documentary filmmaker and I am trying to build battery powered china lantern using an 13w Evolux SH LED array light bulb (http://eartheasy.com/store/proddetail.php?prod=EvoLuxSH).

I'd like to use something like D-Cell rechargable batteries, possibly from a modified light bulb, although since this bulb is made for AC power, I may need some sort of power inverter. It accepts 90~277 V AC.

Does anyone have any ideas about powering this with batteries? The objective is to have it suspended from a cable attached to a pole raised in the air so that we can have light for the camera as we film. Battery powered so we don't have to worry about trailing an extention cord.

You would need an inverter.

Someone found this site in another thread a few weeks ago:

They have other inverters as well as batteries and battery chargers.

If you like the packaging and diffusive dome, you can buy it, strip out the PCB and directly wire to the CREE XRE-LED module using between 2 and 3 1.5V batteries (some 'fresh' alkalines are 1.5V, while fully charged NiMHs or NiCads are 1.2V--under no conditions should you exceed the 3.9V listed on the datasheet):

Or you can just buy the module itself for slightly less and wire it up as suggested above.

EDIT: Clearly, you need an integer value of batteries! I meant to say either 2 or 3 of the 1.2 to 1.5V batteries you have.
